This for sure. More Selfie poses for yourself and with someone else. I want to be able to take full body pics or closeups on the tits and/or dick. Also a "take selfie" interaction with any mirror.
I increased the basic WW levels as the "infection" increased, but more would be better.
Ability to have a sex interaction with the strange plants that you grow and find around town.
The infected try to rape others that are not infected to spread it around. Maybe have tentacles, but definitely a plant "strapon" for the girls.
The plant vines that clog the tub, shower, and toilet could appear while a sim is in the middle of an interaction and try to grab the sim. Cue tentacle sex.
More places for the plant vines to grow and rape the using sim. Like chairs, beds, couches, and the like.
Instead of getting eaten if you fail the boss fight against the mother plant, she tentacle rapes you and infects you.
A sim can be willingly infected by the Mother Plant, which involves getting gang banged by tentacles.
An infected sim could force bring a non infected sim to the mother plant to infect said sim as if they lost a fight.
As for mods I want to see...
I want a way to load more then one lot at a time. Like in Strangerville, I have lot "Slip 42" owned and if I decide to head to 8 Bells, which is across the street, it's a whole loading zone away! I guess it has to do with the fact that the game loads the whole instance as if it was that one lot, so lot traits need to be redone. Like I go home and it has the "teen hang out" lot trait, but if I go to the bar, it has different lot traits.
Expandable lots. I would love the ability to buy more land for my sims. Either by buying an empty lot next door and adding it to the current lot, or expanding the lot bounds as long as it doesn't encroach on other lots or "common lands" like sidewalks, streets, and pubic playgrounds/parks.
More lots. Speaking about StrangerVille, in StrangerVille Plaza there is a ton of fake shops that could have been made into lots(Or "Rabbit Holes" from Sims 3) that the sims could be using for daily routines, places of work, and what not. There is that broken down motel that I would love see turned into something usable. Like a sim buys it and starts fixing it up and stuff. There are quite a few placeholder houses that could become full on lots, which happens more then in StrangerVille Plaza.
More Job compatibility with the "Get to Work" expansion pack. What I mean is, "Get to Work" adds 3 jobs you can follow your sim to and activity control them while at work. I would love to see the base game jobs and jobs from other expansion packs have this level of control. Maybe I want my sim to sleep around while he/she is being a Politician, or watch the crazy stuff happen around the office as a Tech Guru.
Custom adult jobs. Things like being a stripper, Brothel girl, Cam slut, and so on. Maybe work with the above want.
